My invention is an improvement in metallic receptacles and closures therefor and relates more particularly to means for removably clamping covers on containers such as metallic barrels.

One of the objects of my invention is to provide a simple means for clamping the heads on metallic barrels and other recep tacles for storing and shipping liquids such as oil in the form of a split, channelled, contracti le clamping ring for drawing the flan e of the cover ti htly downagainst the bea of the barrel to orm a li uid-tight seal between the cover and receptac e.

Another object of my invention is to provide a removable clamping device for clamping the heads on metallic receptacles such as barrels, which is self-lockingwhen contracted and which may be easily removed from the receptacle to permit access into the interior thereof.

Other objects and advantages of my invention will be more readily understood from the following descriptionof an embodiment 2 thereof, reference being made to the accompanying drawing in which like reference characters are em loyed to designate like parts throughout t e same. 1

Fig. 1 is a side elevation of a metallic receptacle showing my invention applied in use.

Fig. 2 is a plan view of the same.

Fig. 3 is a fragmentary section of the receptacle showing the clamping ring in place and tightly clamping the cover on the receptac e.

In the drawing I have illustrated an embodiment of my invention applied to a metallic receptacle 1 such as a barrel. The receptacle is-usually provided at its open end with a bead rolled outwardly as at 2. A cover 3, having an outwardly extending, annular concave-convex flange 4 fits into t e open end planes to each other. The formation of these 1930. Serial mat-17,320.

of the receptacle as shown, the flange 4 being supported by the bead 2 of the receptacle. An annular packing 5 may be interposed between the flange 4andthe-bead2 to provide a cushion seat for the flange and to further insure a liquid seal when the cover is tightly clamped down on the bead.

In carrying out my invention as illustrated in the drawing I provide a channelled, split clamping ring 6, which, in cross section is substantially shaped. One end of the rin is slightly enlar ed for a portion of its lengt as indicated at for receivingthe other end of the ring 8,'in telescopic relation when the ring-is contracted about the end of therecep tacle for clamping the cover thereon. g I have provided means for securing the ends of the split ring together in interlocked relation when the ring is contracted. This means includes one or more projections or fingers 9 which are preferably formed integrally with the ring material and extend outwardly of the ring end 8 into the path of similar projections or fingers 10 formed on the ring end '11. I

The respective fingers are j preferably formed by stampingjthe same in the ring material and deflecting them. outwardly and inwardly respectively in substantially parallel fingers may be better understood by referring more particularly to Fi s. 4, 5, and- 6 of the drawing, itbeing note that where a plurality of such fingers is employed as shown an opening is provided in the ring materia between each adjacent finger for receiving the respective fingersof the otherend of the ring when the two ends are telescoped one within the other in ring contracted position. The fingers formed in each'end of the rin extend preferably at an acute angle away rom the end walls of the respective ends of the ring.

I have also provided means whereby the ring may be engaged by a suitable tool for contracting the ring in assembling and disassembling it from the receptacle. This means consists in up-setting a portion of the ring material as at 12 and forming an opening through the ring material for receiving a suitable tool for drawing the ring ends together. 100

By my invention I have provided a very simple and inexpensive clamping device for clamping the heads or covers on metallic receptacles which when contracted about the cover and the head of the rece tacle tightly draws the cover and bead toget er to form a liquid-tight seal therebetween. I have also provided means whereby the clamping ring may be easily removed if desired to ermit access to the interior of the receptac e. A clamping ring constructed in accordance with my invention will not become loosened accidentally even though it may be subjectedto severe shock as by dropping the barrel or from other causes.

My invention is intended primaril for use with metallic containers of relatively heavy gage material as, for instance, sheet steel from 10 to 18 standard gage. Liquids such'as oil are stored or shipped in these containers and a liquid tight seal between the bead and the mouth of the container is very essential in such case. By the use of my invention, such a seal ma be maintained while the ring is contracted Various changes may be made in the details of construction andarrangement of parts without departing from the spirit of my invention or the scope of appended claims.

I claim:
